MCX556A-ECAT: Dual-Port 100Gb/s InfiniBand/Ethernet Network Adapter Card
1. Product Overview
The MCX556A-ECAT is a high-performance dual-port network card from NVIDIA's ConnectX-5 series, supporting both InfiniBand and Ethernet protocols at speeds of up to 100Gb/s per port. Designed for data-intensive environments, this nic card delivers ultra-low latency, high message rates, and advanced offload capabilities, making it ideal for HPC, cloud, and storage applications.
2. Key Characteristics
- Dual-port QSFP28 interface supporting 100Gb/s InfiniBand and Ethernet
- PCIe Gen3 x16 host interface
- Hardware offload for RDMA, NVMe over Fabrics, and MPI tag matching
- Support for SR-IOV virtualization with up to 512 virtual functions
- RoHS compliant and energy-efficient design
3. Core Technologies
The network card leverages NVIDIA's ConnectX-5 architecture with support for:
- InfiniBand (IBTA 1.3) and Ethernet (IEEE 802.3bj/bm/by/cd)
- RDMA over Converged Ethernet (RoCE)
- NVMe over Fabrics (NVMe-oF) target offload
- Hardware-based congestion control and adaptive routing
- PCIe Atomic Operations and TLP Processing Hints
4. Working Principle
The MCX556A-ECAT nic card uses an embedded PCIe switch to manage data flow between the host and network. It offloads processing tasks such as packet routing, encryption, and storage protocols directly to the hardware, reducing CPU overhead and latency. The card supports both connection-oriented and connectionless transports, enabling efficient data movement in distributed systems.
5. Applications
- High-Performance Computing (HPC) clusters
- Cloud data centers and hyperscale environments
- NVMe-oF storage arrays and SANs
- AI and machine learning infrastructures
- Virtualized data centers with SR-IOV support
